In the following question, select the number which can be placed at the sign of question mark (?) from the given alternative. 23 ? 12 6 13 7 138 117 84
9
Read the grid by columns. Each column satisfies the rule (top − middle) × middle = bottom.
Column 1: \((23-6)\times 6 = 17\times 6 \ne 138\). Try top × middle = bottom: \(23\times 6=138\). ✓
Column 3: \(12\times 7 = 84\). ✓
So the rule is top × middle = bottom. For column 2: \(?\times 13 = 117\), giving \(?=\dfrac{117}{13}=9\).
